How big a cassette will these work for?
I'm contemplating sticking a chain reaction X O on my full sus as the current mech is wobbly. The medium sized mechs are cheaper than the large size.
Thanks in advance

I run a medium cage x9 on my 44/32/22 and 32T Cassette set up. Works fine. And I can get all 27 gears to work smoothly.

Have been using a medium cage mech, 11-34 cassette and 44 big ring with no problems for a while now. As long as you're careful with your shifting (ie, no big/big crossover) you shouldn't have any problems.

Sounds like the medium will work fine……..now where did I put that credit card
